I recently saw your message (from 2006) when I recently misplaced my copy of the recipe and was looking for it (unsuccessfully) on the Internet. Fortunately, I found my long-time favorite receipe for spaghetti sauce soon thereafter. So, here is the recipe straight from the box:

SPAGHETTI SAUCE

2 Tbsp Mazola corn oil
1 cup chopped onion
3 cloves garlic, minced
1/2 cup chopped parsley
2 cans (28 oz each) tomatoes
1 (6 oz) can tomato paste
2 tsp sugar
2 tsp dried basil leaves
1 1/2 tsp salt
1 tsp dried oregano leaves
1/4 tsp pepper

In 5-quart dutch overn heat corn oil over medium heat. Add onion, garlic and parsley. Cook, stirring, 1 minute.

In blender container place tomatoes; cover. Blend on high speed 30 seconds or until chopped. Add to onion mixture. Stir in remaining ingrediants. Bring to boil. Reduce heat and simmer, stirring occasionally, 45 minutes. Serve over spaghetti.

Makes 6 cups.

MEAT SAUCE:
Follow recipe for Spaghetti Sauce. Cook 1 pound ground beef with onion about 10 minutes or until browned. Makes 7-1/2 cups.

ADDITIONAL NOTE:
I like the meat sauce and make it a little spicy with one addition to the original recipe - dice and add one stick of pepperoni.
